I know that this topic has been probably covered in other posts, but now that I'm flying Arducopter comfortably(from a stability perspective)I’m trying to understand why radio trims are ‘bad’. The reason I say that is that although the auto-trim feature introduced in later versions of the code kind of helps trim the slight imbalances in our frames, the airframes will never always be in 100% CG balance...at least from my limited experience I don't think I've ever managed to fit my battery in the frame in the exact same place every time. I'd like to be able to trim with the remote if I don't have access to a windless environment. I wonder if v2.42 ignores radio trims when it enters into the auto-pilot sort of modes(loiter or RTL)? I thought I read somewhere on this forum that when entering into these modes the software considers the trimmed radio positions as the new centers, can anyone confirm this?
